7 hours

Explanation:

Kelly drives 448 miles on the highway to visit her cousin. She uses cruise control to drive at a constant speed . Kelly travels 192 miles in the first 3 hours. At that rate, how long will the trip take?

Solution:

Speed is the rate of change of distance with respect to time. The speed of an object tells us how fast the object is. Speed is the ratio of distance travelled to total time take, it is given by the formula:

Speed = distance / time

From the question, Kelly travels 192 miles in the first three hours, hence her speed is:

Speed = distance / time

Speed = 192 miles / 3 hours = 64 miles per hour

At constant speed, the time taken to drive 448 miles is:

Speed = distance / time

64 miles per hour = 448 miles / time

time = 448 miles / 64 miles per hour

time = 7 hours

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
